Abstract
An efficient and low cost way to supercharge a four stroke engine is to use the bottom side of the piston to increase the volumetric efficiency. In comparison to naturally aspirated (NA) engines, this supercharging concept pre-compresses the intake air in the crankcase resulting in a significant increase of torque and power output.
On a prototype engine fundamental research activities were carried out on a driven flow test bench to optimize the volumetric efficiency by varying the influencing parameters. Subsequently the characteristics of different mixture preparation concepts (carburetor and fuel injection system) in combination with the treated supercharging concept have been studied during the development phase on engine test bench.
